SHIP-BUFFER.

Specification of Letters Patent. Patented Dec. 18, 191 '7.

Application filed-July 30, 1917. Serial No. 183,490.

'the provision of a buffer adapted to be carried by the hull of a shipadjacent the water line thereof for protecting the hull againstcollisions with other objects such as a boat or wharf.

A further object of the invention is the provision of a plurality ofbuffer plates arranged in parallelism partially surrounding the hull ofa ship, resilient mountin means being provided whereby the shocksincident to striking an object will be-absorbed and cushioned at thepoint of impact, while the hull carrying the device will not be injured.

With these general objects in view and others that will appear asthe'nature of the invention is better understood, the same consists inthe novel combination and arrangement of parts hereinafter fullydescribed and illustrated in the accompanying drawing and then claimed.

In the drawing formin a part of this a plication and in whic likereference 0 aracters designate corresponding parts throughout theseveral views,

Figure 1 is a top plan view of the hull of a ship provided with the,present. device.

Fig. 2 is avertical sectional view through a portion of the device witha portion of the hull shown in elevation.

Fig. 3 is anenlarged elevational view of a portion of the hull and aportionof the device mounted thereon with parts of the device removed,and

Figs. 4 and 5 are sectional detail views taken upon lines IV-IV and VVof Fig. 2.

twill be understood that the device may be arranged upon any buflertherefor, the same being illustrated in connection with a hull 10- of aship having the device surrounding substantially the entire sides andbow portion 11 thereof but being interrupted at the stern portlon 12 ofthe hull. 4

- Elongated guideways 13 are secured upright upon the outerside 14 ofthe hull 10 in form of boat as aparallelism and are provided withmounting blocks 15 slidably mounted therein adapted for receiving theinner ends of springs 16 within the sockets 17 of the said blocks, theouter ends of said springs being seated within similar-sockets 18 ofsuitable heads 19. Elongated strips or buffer plates 20 are secured tothe outer faces of the head 19, whereby the said plates are arranged inplurality substantially surrounding the entire hull 1O excepting itsstern portion 12;

Each guideway 13 may be provided with a desirable number of bufler,lates 20 in the manner herein described, four of the same being hereinillustrateda comprising the complete bufling device. I will be seen thatby this arrangement the mounting guideways 13 and spring carried heads19 may be spaced at suitable distance apart while the forward ends 21 ofthe plates 20 are secured together in advance of the bow 11 of the hull10 and at such point of connection there is preferably arranged a prow22 of suitable material, preferably resilient,

such as rubber. A strip 23'11'1ay also be arranged within the points ofattachment of the opposite plates 20 for connecting each row of platestogether inwardly of the prow 22 while suitable springs 24 are arrangeding adjusting nuts 27 threaded upon the bar at opposite sides of eachhead and whereby as will be apparent, the positions'of theheads 19 uponthe bars 26 may be readily adjusted and retained by means of the nuts27. Retaining screws 28 are also provided for the blocks 15 for hearingagainst the guideways 13 and maintaining the blocks 15 against movementwhen suitably adjusted relatively of the heads 19.

Pivoted struts 29 are arranged at the opposite ends of each rod 26, thesaid struts 29 being pivoted at their inner ends to brackets 30 securedto the hull 10 at points above and below the guideways 13, while theouter ends of the struts 29 are pivoted to collars 31 adjustablyarranged upon the opposite ends of the rods 26 and retained in n devicewhich will still be operative.

capable of absorbing shocks at difi'erent guideways arranged inparallelism secured to the hull, blocks adjustablyarranged in the saidguideways, outwardly pro ecting springs carried by the said blocks,heads upon the outer ends of the said springs, elongated strips carriedby the said heads in parallel superposed arrangement spaced from theside of the hull-and adjustable connections between the said heads.

2. In combination with a hull, upright guideways arran ed in parallelismsecured to the hull, bloc s adjustably arranged in the said guideways,outwardly projecting springs carried by the said blocks, heads upon theouter ends of the said springs,

elongated strips carried by the said heads in parallel superposedarrangement spaced from the side of the hull, threaded rods passingthrough the said heads, retaining means between said heads and rods, andstruts pivotally connected between the opposite ends of the said rodsand the hull at points removed from the opposite ends of a the saidguideways.

aeeaeoe 3.. In combination with a, hull, upright guideways arranged inparallelism secured to the hull, blocks adjustably arranged in the saidguideways, outwardly projecting springs carried by thesaid blocks, headsupon the outer ends of the said springs, elongated strips carried by thesaid heads in parallel superposed arrangement spaced from the side ofthe hull, a resilient prow connected between the forward ends of thesaid plates a strip arranged within said prow between the forward endsof said plates and springs arranged between the said strip and the bowextremity of the hull.

4. In combination with a hull, upright guideways arranged in parallelismsecured to the hull, blocks adjustably arranged in the said guideways,outwardly projecting springs carried by the said blocks, heads upon theouter ends of the said springs, elongated strips carried by the saidheads in parallel superposed arrangement spaced from the side of thehull, threaded rods passing through the said heads, retaining meansbetween said heads and rods, and

struts pivotally connected between the opposite ends of the said rodsand the hull at points removed from the opposite ends of the saidguideways, a resilient prow connected between the forward ends of thesaid plates a stri arranged within said, prow between the orward ends ofsald plates and springs arranged between the said strip and the bowextremity of the hull.

In testimony whereof I aflizrmy signature.
